Reaction de l'azaallyllithium en serie acetylenique: Une methode directe de preparation de phenylethynyl pyrrolidines, -pyrrolines et -pyrroles N-non substitues et N-alkyles

Cycloaddition of 1,3-diphenyl-2-azaallyllithium to tolane, diphenylbutadiyne and 1,4-diphenylbutenyne E produces quantitatively 2,3,4,5-tetraphenylpyrrole, 3-phenylethynyl-2,4,5-triphenyl-3-pyrroline and 3-phenylethynyl-2,4,5-triphenylpyrrolidine, respectively.Treatment before hydrolysis with benzyl bromide or dimethyl sulfate gives N-alkylsubstituted derivatives.The structure of 3-pyrrolines was established by spectral data and chemical correlations.Stereochemical courses of this new synthetic method for 3-pyrrolines are discussed.
